APPARATUS FOR COMPRESSING SCRAP METAL.

S'EGIFICATION forming part of `Letters Patent No. 400,415, dated March26, 1889. Application led December 6, 1888. Serial lla-282,799. (Nomodel.) Patented in England September 1, 1888, No. 12,598.

To all whom, it may concern:

Beitknown that we, JAMES WOOLLEY SUM- MERs and TREVELYAN SHARP, subjectsof the Queen of Great Britain and Ireland, of Stalybridge, in the countyof Lancaster, England, have invented certain Improvements in Apparatusfor Oompressin g Scrap Metal into Blocks or Slabs, (for which wehaveobtained a patent in Great Britain, No. 12,598, dated September 1,1888,)of which the following is a specification.

Our invention relates to apparatus adapted to be employed in compressingor condensing scrap metal into blocks which can be heated and rolledinto plates or bars. We employ four hydraulic rams, three actinghorizontally, the fourth being arranged to press downward upon the massconsisting of scrap which has been compressed into a smaller compass bythe three horizontal rams.

In order that our invention may be clearly understood, we will describethe same more fully with reference to the accompanying drawings.

Figure 1 is a front elevation of the machine. Fig. 2 is a plan ofthemachine.

' In the said figures, a care two rams, which Work in the hydrauliccylinders A A and move on the same horizontal plane toward and from eachother. A third ram, b, works in the hydraulic cylinder B and moves on ahorizontal line at right angles with the line of movement of the tworams a a. The three cylinders A A and B are firmly mounted and keyed orsecured upon and to a strong cast-iron foundation-bed, c. The uppersurface of this bed forms the floor of the machine and receives thescrap which is to be operated upon. Each of the rams a a is providedwith a rectangular head or follower, a', which slides upon the bed. cwhen the rams are worked in or out. The third ram, b, is also providedwith a head, h', which corresponds in height with the heads a', but ismuchlonger.

On the opposite side of the machine is a strong upright ymetal wall, d,which is cast in one piece with the bed, or is firmly bolted, keyed, orsecured to the same, as preferred. The vertical face of this Wall isparallel with the vertical face of the head b and corresponds in heightwith the same. When the heads a slide toward or from each other, thevertical sides which are next to the face of the said wall move insliding contact with the face of the said wall, or may clear the same toa suitable extent. If preferred, the upper surface of the bed and thefaces, edges, or other parts of the heads and wall maybe planed. It willbe seen that when the head b is pushed close up to the heads a the threeheads, the wall d, and the bed constitute a rectangular box, which isopen at the top. To the bed c are firmly secured four strong columns, e,which carry a press cross-head,f. Seated in this cross- ,head is afourth hydraulic cylinder, G, in

which works a ram, h, of larger diameter than any of the other three.The lower end of this ram is provided with a head or follower, 71,',which is of about the same width on the face as each of the two heads a.One side of this head moves in sliding contact with or in closeproximity to the wall d, as in the cases of the heads a..

Suitable pipes and connections are provided for connecting the severalram-cylinders with an accumulator or with hydraulic pumps, or with both;but it has not been considered necessary to show such parts in thedrawings. A small hydraulic cylinder, t', is mounted above the cylinderG, and within the said cylinder i is apistomwhich is connected by meansof a piston-rod, i', with the upper end of the ram h. By admittinghydraulic pressure below the said piston the ram h is raised after eachoperation. In the example the rams a and b are arranged to be drawn backby means of weights and chains la k; but, if preferred, they might bedrawn back by hydraulic pressure. In the cases of any of the ramsthe'ram might have a piston-head, so that the ram could be drawn back byadmitting the pressure into an annular space on the front of suchpiston-head. The head l of a small ram which works in a cylinder, Z,isseated in a recess in the lower part of the center of the wall d, sothat when the ram is withdrawn into the cylinder the face of the saidhead is flush with' the wall d, and practically constitutes a part ofthe same. The use of this ram and head will be explained hereinafter.

The machine is intended to be used in manner as follows: When the partsare in the positions indicated in the drawings, the scrap to becompressed is placed upon the bed c within the space, which is inclosedon four sides by the parts a', d, and ZJ', with the exception of the twoend openings at m m, between the heads a and the two ends of the head b.The said space is lled completely, or to a desirable extent with thescrap. The ram b is then pumped or forced; toward the wall d until ittouches or nearly touches the two heads a and the front edge'of the head72', thus com-L from below the head h', so that the slab can readily bewithdrawn through one of the afore-v said end openings m. The slab maybeheated i and rolled, hammered, or treated to convert it into bars, rods,or sheets, as required. If not considered to be necessary, the parts Zand l maybe dispensed with. lf preferred, the said end openings, m m,may be closed by means of vertical walls oroi hinged or movabledoors,which or one of which might Abe opened for the removal of the slab; orone or each of the cylinders A might be mounted so that it could beturned out of the way for the removal of By means of our improvedmachine the slab.
